Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518718, here are decompositions:

19 + 518699 = 518718
29 + 518689 = 518718
61 + 518657 = 518718
97 + 518621 = 518718
107 + 518611 = 518718
131 + 518587 = 518718
139 + 518579 = 518718
197 + 518521 = 518718

Showing the first eight; more decompositions exist.
